The tool processes a scanned multi-column research paper end-to-end and returns OCR text, tables, and embedded chart assets in page-wise markdown output.
What was measured
Complex Document Handling
Maintains quality across long, multi-section, and mixed-content documents without degradation.
decisive for this rankingtransformation
The subject explicitly says complex PDF, so sustained quality across long, mixed-content documents is central to the tool’s ability to do the job. (3 of 3 judges)

Test input: Scanned Research Paper · pdf · group: scanned-research-paper
Input — what we sent
Scanned Research Paper
An image-only scanned research paper used to stress OCR and layout recovery in a multi-column academic document with figures, charts, tables, captions, and references.
Why this input is hard
- · OCR on scanned pages
- · Multi-column reading order
- · Figure and chart handling
- · Table reconstruction from scans
- · Caption association
- · Reference extraction
- · Overall document structure retention
Output — unretouched
Also checked on this input — same tool, 7 other criteria
Markdown Quality✓ WorkedThe export is packaged as usable markdown files in a ZIP, with both overall and page-wise outputs available for inspection.Reading Order & Structure✗ FailedThe opening page loses the distinction between the document title and the abstract, flattening the semantic organization of the first page.Reading Order & Structure✓ WorkedSection hierarchy and reading flow are preserved in the scanned paper, keeping headings and supporting paragraphs correctly connected despite the multi-column layout.Table Preservation✓ WorkedThe multicolumn table is reconstructed without losing its overall layout logic, so the table structure remains readable in the parsed output.Table Preservation✗ FailedBroken column boundaries and disrupted value alignment make the reconstructed table significantly less faithful to the source.Text & OCR Completeness◐ MixedThe report says the parser recovers much of the underlying text from the scanned paper, but it does not present a measured completeness rate and the first-page hierarchy is still lossy.Visual Content Retention✓ WorkedCharts are exposed through both page-wise markdown files and the extracted visual assets, keeping the visual content linked to its original document location.

Adobe API⚠ StruggledRequires splitting an oversized scanned paper into two PDFs before processing, because the web interface rejects uploads over 1 MB.Extend AI✓ WorkedHandles the scanned research paper end-to-end, including multi-column prose, tables, charts, and handwritten marginalia, while still producing parsed markdown.LlamaParse✓ WorkedProcesses a 12-page scanned paper end-to-end and reaches SUCCESS after extracting the page content and figure/table outputs.Nutrient.io✓ WorkedProcesses an image-only scanned research paper end to end and returns a parsed markdown output plus preview, showing it can handle a multi-page scanned document.Reducto⚠ StruggledHandles the 12-page scan in 10.6 seconds with no truncation, but the densest 17-column table has unreadable stretches with injected glyphs and run-on numbers.Tensorlake◐ MixedOn the scanned research paper, section flow and chart extraction work, but hierarchical tables degrade, so mixed-content handling is uneven rather than consistently robust.
